UNDERFRAME FOR RAILWAY-CARS.

To all lwhom 'tt lmay concern'.-

Beit known that I, EDWARD PossoN, a citizen ofl the United States, residing at Chicago, 1n the county of Cook and State of Illinois, have invented certain new and useful Improvements in Undert'rames for Railway-Cars, of which the following is a speci- 'icatioxn The Objects of my invention are toprovide a new and improved body bolster for cars, and to combine the body bolster with the I center sill in an advantageous way. Y

j Referring to the drawings-Figure 1 is a plan )new of my improved body bolster, in combmatlon' with a center sill. Fig. 1a is a Asection of the bolster vtaken on the line 1a in Fig. 1. V Fi-g. 2 is a longitudinal sectionotl the bolster taken on the line 2 in Fig. 1. Fig. 3 is a plan View of a modification in which the center sill extends only in one direction from the body bolster.' Fig 4 is a section on the line 4 in Fig.. 3, looking in the directionof the arrow. Fig. 5 is a 4plan view of a modified bolster; in combination with a center sill. Fig. 6 is a section on the line 6 in Fig. 5, looking in the direction of the ar- .A row. Fig. 7 isa plan view of a modification in which the center sillextends in only one direction' from the bolster.

webs 18 radiate.l

` of the bolster, and top plates 21 and bottom plates 22 lap over the ends of the channel beams 20 and across the bolster 15 and are riveted to all of these members. The bolster slopes upwardly toward the ends on its under side, as illustrated in Fig. 2, and therefore the plates 22 are bent so that one surface can be riveted to the channel beams Q0 and another surface can be riveted to the lower flange of the bolster. In cases where Specication of Letters Patent. Patented NOW-16, 1909. Application fuea october 21, 1907.

seriaim. 398,464. y 1 H the greatest degree of strength is not considered necessary, it may be ex edient to have the channel beams 20 exten only between the body holsters 15 and the corresponding ends of the car; that is, the channel beams 20 may be omitted between the two body `bolsters. Fig. 3 illustrates this modication. In this 'ase the under plate 22a is preferably made considerably wider than the correspoiiding under plate 22 in the modifica-tion" in Fig. 1.

In the modilicaton of Figs. 5 and 6 the bolster consists of two parallel I-beams 15b spaced apart slightly. Their webs are represented by the reference character 16h. Yokes 18b are riveted to the inner sides of the webs 16h, and so shaped vas to form the hole 17 rfor the king-bolt. In this modification the under plate 22h extends clear across from one channel beam 20 tothe other. A

F ig. 7 villustrates a modification which dit'- fers from that of Figs. 5 and 6 only in that the center sill channel beams between the twoholsters have been eliminated, as has already been explained in connection with Figs. 3 and 4, and the under plates. 22 do not` extend continuously across but are like those shown in Fig. 1.

In this improvement 'the body bolster extends continuously from one side of the car to the other and the center sill men'lbers abut it and are securely attached thereto. Thus desirable rigidity of the body bolster is secured and at the same time the center sill is adaptedl to withstand the butliug or pulling stresses to which it may be subjected.

W`hat I claim iS l. In a car, a body bolster having an I-sec tion with a diminishing width of web thereof toward the ends of the bolster, the under flanges thereof sloping upwardly from the center toward the sides of the car, center sill channel beams with their ends abutting' the said bolster, and four gusset plates overlapping the joints between said channel beams and the bolster both above and below.
